Why is this still in the game? I get that it was implemented between TBC and wrath to prevent dungeon boosting. BUT! FAT SPOILER BLIZZ! People are still boosting! This prevented nothing BESIDES MEGA Grifing anyone who wants to run old content!
So far its only been in old NM dungeons, which by your logic i get, prevent boosting. But WHY the F*** is it in KARAZHAN???
Just remove this dumbass mechanic from the game already! No one wants this and it serves no purpose what so ever since Boosting is still a thing and more alive then ever!
